To all whom it may concern.- to open either in unison or separately, sothat, Be it known that we, W'ILLIAM DOWNS, reif desired, part of theeconomizer can be siding at New York, in the county of New workedcirculating and part non-circulating.

The two sets opening the wing-valves, which are arranged ofvalves are disposed in alternation, relatively to each other, as shownin the drawings. ,7

The valves are essentially of the wing variety, and consist of metaldisks fitted suitably in the pipes, and mounted on journals or stems 8,let through guides or caps 9, and carryingon their outer ends arms 10,the free ends of which are detachably connected to a valve-rod 11, sothat they can all be opened and closed by a single movement of thevalverod,or so that by removing the pivot-screw 12, which holds the armsto the valve-rod, any number of the valves may be opened, that part ofthe economizer converted into a natu ral circulating apparatus, and thebalance of it be used as a positivel y-circulatin g apparatus.

To use the apparatus as a positively-circulating one, the valves are allclosed, and then the water will be directed back and forth across theapparatus, flowing up one tier and down the other; and if it is desiredto convert the apparatus into a non-circulating economizer the valvesare all opened.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is'

1. In a fuel-economizer or feed-water heater, the combination with thenest of pipes, the feed-pipe 2 connected with one tier thereof, the toppipe 4 communicating with the other end ofthe pipes of said tier, a toppipe 5 communicating with the top pipe 4 and with one end of the nest ofpipes of another tier, a bottom pipe 7 at the opposite end of the pipesof the last-named tier, a blow-off pipe B communicating with the bottompipe 7, the combined access and blow-off pipe B having communicationwith all the tiers of'pipes at one end, the top delivery header or pipeB having communication with the opposite ends of all the tiers of pipes,and valves alternately disposed in the feed-pipe and the deliverypipe,whereby the apparatus may be converted from a non-circulatin g into apositive circulating apparatus.

2. In a f uel-economizer or feed-water heater, the combination with thenest of pipes, the feed-pipe 2 connected with one tier thereof,

the top pipe 4 communicating with the other end of the pipes of saidtier, a top pipe 5' communicating with the top pipe 4: and with one endof the nest of pipes of another tier, a bottom pipe 7 at the oppositeend of the pipes of the last-named tier, a blow-off pipe B communicatingwith the bottom pipe 7, the combined access and blow-off pipe B havingcommunication with all the tiers of pipes at one end, the top deliveryheader or pipe B having communication with the opposite ends of all thetiers of pipes, and valves alternately disposed in the feed-pipe and thedeliverypipe, arms on the stems of the valves, and a valve-rod on thefree ends of the arms, whereby the valves may be opened and closed inunison.

3. In a fuel-economizer or feed-water heater, the combination with thenest of pipes, the feed-pipe 2 connected with one tier thereof,

the top pipe 4: communicating with the other end of the pipes of saidtier, a top pipe 5 communicating with the top pipe 4 and with one end ofthe nest of pipes of anothertier, a bottom pipe 7 at the opposite end ofthe pipes of the last-named tier, a blow-off pipe B communicating withthe bottom pipe 7, the combined access and blow-off pipe 13 havingcommunication with all the tiers of pipes at one end, the top deliveryheader or pipe B having communication with the opposite ends of all thetiers of pipes, and valves alternately disposed in the feed-pipe and thedeliverypipe and formed with stems, arms in the ends of the stems, and avalve-rod detachably connected to the ends of the arms, whereby some orall of the valves may be operated by the valve-rod.

In testimony whereof we hereunto affix our signatures in presence of twowitnesses.
